Answer:

A. Neon and argon

General Formulas and Concepts:

Reading the Periodic Table of Elements
Valence Shell configurations

Explanation:

Elements that have a full valence shell (the outermost shell), are in Group 18 of the Periodic Table.

Because their outermost shell is full, they are inert, meaning that they do not like to bond or react with other elements.

Therefore, these gases with a stable full valence shell are known as Noble Gases.

Helium
Neon
Argon
Krypton
Xenon
Radon
